Abstract：
BACKGROUND: This study aims to assess the association of operative time with the postoperative length of stay and unplanned return to the operating room in patients undergoing femoral to below knee popliteal bypasses, stratified by autologous vein graft or polytetrafluoroethylene (PTFE).
METHODS: A retrospective analysis of vascular quality initiative database (2003-2021). The selected patients were grouped into the following: vein bypass (group I) and PTFE (group II) patients. Each group was further stratified by a median split of operative time (i.e., 210 min for autologous vein and 155 min for PTFE) to study the outcomes. The outcomes were assessed by univariate and multivariate approach.
RESULTS: Of the 10,902 patients studied, 3570 (32.7%) were in the autologous vein group, while 7332 (67.3%) were in the PTFE group. Univariate analysis revealed autologous vein and PTFE graft recipients that had increased operative times were associated with a longer mean postoperative length of stay and a higher incidence of all-cause return to the operating room. In PTFE group, patients with prolonged operative times were also found to be associated with higher incidence of major amputation, surgical site infection, and cardiovascular events, along with loss of primary patency within a year.
CONCLUSIONS: For patients undergoing femoral to below knee popliteal bypasses using an autologous vein or PTFE, longer operative times were associated with inferior outcomes. Mortality was not found to be associated with prolonged operative time.

摘要：
背景：本研究旨在评估股骨膝下动脉旁路手术患者手术时间与术后住院时间和计划外返回手术室的关系，通过自体静脉移植或聚四氟乙烯（PTFE）分层。
方法：血管质量倡议数据库（2003-2021）的回顾性分析。将所选择的患者分组为以下:静脉搭桥(I组)和PTFE(II组)患者。每组按手术时间的中位数进一步分层(即，自体静脉210分钟，PTFE155分钟）研究结果。通过单变量和多变量方法评估结果。
结果：在研究的10902名患者中，自体静脉组3570例(32.7%),PTFE组7332（67.3％）。单变量分析显示，手术时间增加的自体静脉和PTFE移植受体与术后平均住院时间更长和全因返回手术室的发生率更高相关。在PTFE组中，手术时间延长的患者也被发现与较高的严重截肢发生率有关。手术部位感染,和心血管事件，以及一年内失去初级通畅。
结论：对于使用自体静脉或PTFE进行股骨至膝下动脉旁路的患者，较长的手术时间与较差的结局相关.未发现死亡率与手术时间延长有关。
